In the multimedia device control apparatus according to the present invention, a display state of a warning message according to a risk level is shown.

First, while the vehicle is running (S10), the driving environment determination unit 22 of the electronic control unit 18 is the steering sensor 10, gyro sensor 12, vehicle speed sensor 14, ABS sensor In operation S11, the controller 16 receives a steering detection signal, a gyro detection signal, a vehicle speed detection signal, and an ABS detection signal according to the results of the sensing operation, respectively (S11).

In this state, the driving environment determination unit 22 weights the sensing information of each sensor based on the weight information stored in the memory 20 and the score calculation reference information for each weight, and according to the assigned weight. The score is converted (S12), and the driving environment level determined according to the converted score result is determined (S13).

Meanwhile, the multimedia determination unit 24 of the electronic control unit 18 receives and collects device operation event information generated according to the driver's device operation from the multimedia device 100 installed in the vehicle (S14). The score is converted based on the variable information according to the event type stored in the memory 20 and the score calculation reference information for each event (S15), and the driver is derived by deriving an operation result level determined according to the converted score. The apparatus operation state is determined (S16).

Then, the diagnosis unit 26 of the electronic control unit 18 comprehensively diagnoses the driving environment level from the driving environment determination unit 22 and the operation result level from the multimedia determination unit 24. The diagnostic level is assigned based on the information stored in the memory 20 (S17). It is determined whether the diagnostic level has a level value included in the range of dangerous driving (S18).

As a result of the determination, if the diagnosis unit 26 determines that the currently provided diagnosis level is a level value that is not included in the range of dangerous driving, no further information processing is performed, but the diagnosis level is included in the range of dangerous driving. If it is determined that the level value is, the execution command of the diagnostic level corresponding to the degree of dangerous driving, that is, the risk level, is output to the limit instruction execution unit 28 (S19).

Therefore, the limit command execution unit 28 according to the execution command of the diagnostic level from the diagnosis unit 26, based on the warning message information and control command information for each risk level stored in the memory 20, the warning message Control to output the speaker 30 and the display unit 32 or the audio output unit 112 and the video output unit 114 of the multimedia apparatus 100 or limit the use of the device to the multimedia apparatus 100. The command signal is output (S20).

Accordingly, in the case where the risk level is a mild risk, as shown in FIG. 3A, a warning message such as “use of the device while driving may be a safety hazard” may be outputted as voice and screen, Control to limit the operation of the equipment is not performed.

In addition, when the risk level is a medium risk, as shown in FIG. 3B, a warning message including a content of a lesser recommendation, for example, "We recommend using a hand remote control for safe driving," is voiced. And screen output, and control for restricting operation of the device is not performed.

However, when the risk level is a high risk, as shown in FIG. 3C, for example, the key button except for the power and volume of the main body of the device operates only as a remote controller key for safe driving. A warning message for notifying the contents can be outputted as a voice and a screen, and a control command signal for limiting the operation of the multimedia apparatus 100 is generated.

Accordingly, the multimedia controller 106 of the multimedia apparatus 100 restricts the execution of functions for the input of the remaining key buttons except for the input of some key buttons of the key input unit 102, and the wireless remote controller from the remote controller 104. Only in response to the signal will the function execution be controlled.
